question about 3640's and max flash/mem 40/256mb ? Anyone?

Hi,

I have searched the cisco kb and docs for a answer but have found none.
most docs say max for 3640 is 32mb flash and 128 mem. Thats what I have now on my 3 3640's. Some ios images for 3640's have flash req of 40/192-256? I'm guessing that the 40 flash comes from the rare and expensive 40mb pcmcia flash card. but the extra ram? will 3640 take 64mb sticks of ram? Do you need a bios upgrade chip? Has anyone done this? Probably is a waste of time anyway as I bet it would only matter for ISP use which this platform is to slow and old for anyway but if I can get it cheap than its worth a try.

Anyone know where to get the cheap larger type pcmcia flash cards for 36xx series other than ebay?

thanks

    Hi,

    I sold my 2 3640 routers and buy 2600xm routers, max memory for 3640 are 128/32, also they not support the latest 12.4 IOS (exactly c3640-jk9o3s-mz.124-16.bin) check here: http://www.techexams.net/forums/viewtopic.php?t=33485 , i added a external flash and nothing, if you want buy a pcmcia flash cards you can buy the one for the 1600 series routers, i got one and it worked very good.

    Hope this help. icon_wink.gif icon_wink.gif

    Hi,
    thanks elegua for info but I still can't believe that when I log on to my cisco account for downloading IOS images for 3640 platform and it comes up with many new just released images that say 40/192 that they all are wrong. The one problem I have is that I don't have a 40mb card for testing.

    To sum it all up are you sure that the 100 or so new images that are listed are all wrong? Why would they build a image for 3640's for them to not work. Maybe it is limited release images only for ISP's and such. Does your account show many 12.4 images as 40/192 ? like mine?

    thanks

    Cisco have been wrong before.

    All the 12.4 images I can see on the site have a maximum RAM of 128MB and a maximum flash of 32MB. What IOS file are you trying to load anyway?

    I can't find any that have the requirements you listed?

    I can't find the ones that had 192mb.But they were there 5-6 months ago. They seem to be removed. Some of the 40mb flash ios's are still there, here is two

    c3640-a3jk9s-mz.124-10c.bin Minimum Memory: DRAM:128MB Flash:40MB
    c3640-jk9s-mz.124-10c.bin Minimum Memory: DRAM:128MB Flash:40MB


    well I guess it does not matter now that they are no longer listed. I do have special account so maybe they were limited and were pulled but I am not making this up or mistaken. I asked a few of my CCIE/NP's coworkers about the larger than listed req but they could not figure out at the time how to get more than128dram installed into 3640's and I was in no rush as I was not studying for BSCI at the time so I let it go.

    I wouldn't worry about flash to much since you can store the ios on a tftp server.

    Ah. I didn't search all the way back to 12.4.10. Weird that there aer 3 images listed needing 40MB of flash. Its probably a mistake by Cisco though on those if it is just flash. They admitted to messing up some others which needed more than 32MB.

    thanks kryolla
    Didn't think of using TFTP.

    Feel stupid that I didn't think of that from the start.
